(observation thread) 4.2.2 discussion

bongostl said:

Hey all

I thought I works start a thread to discuss our observations of the update. This day we can keep other threads clean.

First and foremost, the n7 feels smooth again to me.

I was really sick of how slow it felt on 4.2.1....this seems to have fixed that.

I agree smoother and much faster it seems, boot was almost instant, I installed a game I use to play and it starts faster and runs better. Can say I am very pleased.

Guys whats are the changelog? Is the mediaserver battery eating problem/bug solved?

Although ADB from a PC works fine, ADB in loopback mode on a rooted device seems broken:

starting adb in loopback (commands entered on the device itself):


any adb command after that (like "adb shell ...") will fail with "error device offline", which is confirmed with adb devices:



This worked perfectly in previous versions...

This must be related to Google enforcing RSA authentication with ADB: http://xdaforums.com/showthread.php?t=2144709

Probably, and this is going to break some mount scripts that use this ability to call adb shell in loopback mode.

As if mounting was not already overly problematic since 4.2...

Agreed feels smoother than 4.2.1 before upgraded to 4.2.2 I would encounter lag anytime there is any WiFi data transmission, eg... when downloading and installing an application, when updating or syncing an application, thing use to lag till WiFi was done transmitting and doing whatever it was doing. It seems fine now on 4.2.2

Happy with my n7 again!!!

It actually seemed a lot slower than 4.2.1 at first, but, after a few reboots, the butter is back. I didn't notice that I lost root until I rebooted a few times, so that could've been the cause of the lag, as apps were probably looking for su in the background.

I'm yet to install it but here's the changelog from wiki:

Fixed Bluetooth audio streaming bugs[102]
Long-pressing the Wi-Fi and Bluetooth icons in Quick Settings now toggles the on/off state
New download notifications, which now shows the percentage and an estimated time remaining for your app downloads while they are happening
New sounds for wireless charging and low battery.
Removed option to show all calls in the phone app's call list.
New Gallery app animation allows faster loading.
USB Debug whitelist
Bug fixes and performance enhancements

Just curious on how soon Devs roll out updates to their Roms,Kernels and Toolkits. This was my first OTA on a custom rom so I am eager to get back to my custom tablet.

There's already one ROM with updated Gapps for 4.2.2 also, the codefireX ROM here:

I'm sure we'll see 4.2.2 spread like a plague soon enough with all the usual participants.

They finally fixed the "recent apps re-appearing if you switch from landscape to portrait (or vice-versa) while removing them" bug. (that was a mouthful)

Based on some initial less than positive reports of performance issues with Android 4.2, I kept my Nexus 7 wifi at 4.1.2.

Should I take take the leap and upgrade to 4.2.2 now, or wait a bit before doing so for the OS to be more thoroughly evaluated?

they also (finally) fixed the ugly gradient !

I don't see much of a difference on 4.2.2 really. But it isn't worse anyway! LOL

I do miss my custom rom features and options. I certainly will be flashing custom 4.2.2 roms as soon as they start dropping!

A full factory ROM flash, of course, there's no one to simply "roll it back" to 4.2.1 - you're gonna have to start clean and fresh.

Well if it wasn't for the adb issues that would be easy and i wouldn't ask.

See above.

Your best bet is to fix your ADB issue.

I'm running 4.2.2 rooted and unlocked for the 3rd time in two days now (since it was released) and I've yet to encounter any so-called "issues" with ADB like so many others seem to be having. I have the latest Android SDK drivers direct from Google since those are truly the only ones anyone should be using, period, and I've flashed/reflashed/rooted/unrooted/locked/unlocked in both Windows 7 and Ubuntu several times now without a single issue either.

Not sure why people have so many issues with these things, all the info you require is out there - I read the same threads everyone else does but it sure seems like everyone else reports problems 100x more than I've ever even encountered personally.

If you want to go back to 4.2.1 you're going to have to flash the 4.2.1 factory image from Google, and there are like 9 ways to do such a thing, the most obvious and sure-fire method is using one of the toolkits but you must - I repeat you must have the ADB drivers working properly if it's Windows, and again the only ones I'll even bother with are from Google direct (the ones I'm using right now were pulled from the most current SDK and are dated 8/12/2012 with a version number of 7.0.0.1).

Once that's accomplished both ADB and fastboot work without issues for me, never had a problem at all worth even mentioning and I have 11 Android devices that I mess around with near-constantly from this Nexus 7 all the way back to my trusty HTC HD2.

If you can't get it working in Windows, then Ubuntu is the next best course using the instructions at the bottom of this page to flash the Nexus 7 back to pure stock 4.2.1 which works flawlessly:

https://wiki.ubuntu.com/Nexus7/Installation#Returning_your_Nexus_7_to_Stock_Android

Note: you have to install that Ubuntu Nexus 7 Desktop Installer thing at the top of that page, takes seconds to install (it's just a tiny GUI for command line tools but you won't be using the GUI, it handles the drivers and ADB/fastboot setup as well).

If you're unable to get it functional with that info, well... 4.2.2 ain't bad at all, really.
